DIE MOUNTING.

Application led February 10, 1922.

To all whom t may concern:

Be it known that l, CHARLES A. Knorr, a citizen of the United States,and a resident of the city of River Forest, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in DieMountings, of which the following is a specification. y

My invent-ion relates to improvements in die mountings, especiallyadapted for use on drop hammers, punch presses and the like, and has forits object the provision of an improved construction of this characterby means of which dies for such machines may be economicallymanufactured and readily and securely mounted on such machines.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanying'drawings forming a part of this specification, and in which, y

Fig. 1 is a top plan view of a construction embodying the invention;

Fig. 2 is a top plan view of the die holder employed in saidconstruction;

Fig. 3 is a bottom plan view of the die body illustrated in 1;

Fig. l is a transverse section taken on line 4 4 of Fig. 1; h

Fig. 5 is a side view of the construction; and

Fig'. 6 is a horizontal section taken on line G-G of Fig'. ll.

The preferred form of construction as illustrated in the drawingscomprises a die holder 7, the body of which is of any usual or desiredconstruction for mounting in a drop hammer, punch press or the like. Theupper surface of the body 7 is provided with a linished surface 8adapted and arranged to constitute a seat for the die body, and asubstantially semi-circular socket 9 is arranged substantially centrallyof the surface 8. The circular side 10 of the socket 9 is undercut orbeveled as shown, and the portions 11 of the walls of said socket formedvertical, a taperingv inclined keyway 12 being' cut in the body 7traversing the side of the socket 9 opposite the under out wall 10. Thedie body 13 -is provided with a flaring stem 14 arranged to fit betweenthe walls 11 and flared to Serial No. 535,483.

nicely fit the undercut wall 10. rlhe side 15 of the stem la isflattened and beveled to correspond to and register with thecorresponding' side of the keyway 12. The under` sur* face of the diebody 13 is nicely finished to rest upon the surface 8 and the bottom ofthe stem 14; is nicely finished to rest upon the bottom of the socket 9.A taperingor wedge-shaped key 16 is tted into the socket lf2 to contactas shown with the flattened side 15 of the stem 1lfor holding Said stemand said die body in place. The die body 13 may be provided with anydesired form of die 17, the one indicated being a die for a 2(rearblank, as will be readily understood.

By this arrangement the die body may usually be made of circular stockor material to be finished in a lathe, which ,greatly facilitates theprocess of manufacture and the economical production thereof. A firm andsecure seat and support is also provided for the die body wherebymovement thereof under the heavy strains incident to use is prevented.Likewise there is and can be no strain or pressure upon the locking keyso that it is impossible for the die to work loose in use. rllie form ofconstruction illustrated is one capable of very economical manufactureand production, from `a minimum of stock. The specific form andarrangement of parts illustrated is a simple and effective one for thepurpose.

While l have illustrated and described the. preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. l, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modiiications as come within the scope of the appendedclaims.

Having' described my invention, what I claim as new and desire to secureby Letters Patent is:

1. A die mountino comprising a body provided with a stem; a holderhaving?,` a socket therein somewhat larger than said stem to permitdirect insertion of said stem and lateral movement of said stem in saidsocket` the walls of said socket and the sides of said stem beingarranged to engage with each other upon lateral movement of said stem insaid socket; and means for securing said stem in said socket ininterlocking,` relation with the walls thereof, substantially asdescribed.

2. The combination with :L die body provided with a circular stem having:t flattened side, of u holder having),` it substantially semicirculursocket therein, said stem being adapted and arranged to be inserted insaid socket und engage therewith by lateral movement therein; und ineensengaging' the fluttened side of said stem for locking' the same in saidsocket, substantially es described.

3. A die mounting' comprising a. holder having a substantiallysemi-circuler socket therein and u key way traversing' the flat side ofsaid socket; e die body provided with e substantially circuler stemhaving;` u flattened side fitting into said socket and engaging;therewith by lateral movement therein; und a key insertable in seid keyway and engaging' the fiattened side of seid stem to secure the stem insaid socket, substantially as described.

4. A die mounting' comprising a holder having e substantiallysemi-circuler socket therein, the circular portion of said socket ibeine under eut there beineV u ke wa. f trav- 'ersing the flirt side ofsaid socket; e die body provided with a substentiallvconieal stem ittingwithin said socket und having e lattened side; and u wedge shaped keyinsertavble in seid key way and engaging the flattened side of said stemto secure the same in said socket, substantially as described.

5. A die mounting comprising :i holder having a socket therein, the oneside of the wall of Suid socket being' undercut and 5L keywuytraversing` the other side of seid socket, the intermediate walls ofsaid socket being straight; a. die body provided with a stem adapted tofit between seid straight walls of said socket, seid stem being flaredto fit the undercut wall of Said socket, the side of said stemcorresponding` with said keywzty being beveled; and a wedge-shaped keyinsertable in seid lieyway and engaging' the bevelled side of suid stemto secure the same in Said socket, substantially as described.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing' witnesses.
